Abstract
A first object of the invention is to provide a control circuit (1) for gas burners with a fail-safe system. The circuit (1) includes a microcontroller (2) that acts on at least one valve (4), flame detector circuits (50) and tap opening detector switches (6). For each valve (4) the circuit (1) has a plurality of switches by means of which these valves are supplied with the voltage required to open them and keep them open. The microcontroller (2) governs said switches in accordance with the signals it receives from the circuits (5), from the switches (6), and from points of the actual circuit (1). The circuit (1) is safe against the failure of any of its components, including the microcontroller (2). A second object of the invention is also to provide a circuit (1) that has protection against a double failure.
